Application November 3, 1930. Serial No. 493,124 1 claim. (c1. 184-6) This invention relates to lubricating systems for machine elements, such as Athe rocker arms v 1 duits may be adjusted with relation to the rocker of overhead valve engines and the like.

One of the principal objects ofthe invention 5 consists of a system of this character embodying a lubricant reservoir located in juxtaposition to the rocker arms.

An additional object of the invention contemplates the provision and arrangement of conduits 1Q; between the rocker arm covers and the reservoir having lubricant saturated wicks vpassed therethrough. Y 1

More specifically stated the conduits are provided with adjusting means to regulate the clearance and adhesion of the wicks with the rocker arms.

With the above and other objects in view, the invention further consistsV of the following novel features and details of construction, to be herezuinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claim.

In the drawing:- Figure l-is a fragmentary longitudinal sectional ViewV taken through the invention as applied upon the cover for `the rocker arms of an overhead valve engine.

Figure 2 is a horizontal sectional View taken through the cover and reservoir. K v

Referring to the drawing in detail wherein like characters of reference denote .corresponding parts, the reference'character 10 indicates generally the engine of the overhead valve type having a shaft 11 supported at intervals by blocks 12 and having rockingly mounted therebetween the sleeve like journal portions 13 of rocker arms 14. All of the above is ofthe usual yand well known construction ollowed in the manufacture of engines of the character described and which forms no 40, part of the present applicationI for Letters Patent but which is merely mentioned for purposes of illustration in bringing forward the novel advantages of the invention. ,l

Engines of this character also include covers 15 of elongated substantially inverted trough shape to prevent the accumulation of extraneous matter upon the valve stems and rocker arm mechanism. It is ourpurpose to utilize this cover in the manner suggested in the drawing so `by perforating the same at intervals'upon the top thereof immediately above those ends ofthe rocker arms having engagement with the extremif ties of the valve stems. Conduits 16 of tubular formation passed through the aperturesor perforations carry locking or adjusting nuts 17 located upon opposite sides of the cover for frictional engagement therewith whereby the conarms. These conduits also project upwardly within the bottom of the lubricant reservoir 18 and to support same'in the positions shown. Wicks 19 of any suitable description and material-having a high degree of absorption characteristics are passed through the conduits and project outwardly beyond the extremities thereof for appreciable distances. Cap members 20 may be carried upon the uppermost ends of the conduits within thev lubricant reservoir for abutting engagement ywith the adjacent wall of thereservoir and to prevent too much of the oil passing through the conduits when the lubricant is splashed within the reservoir. It is our intentionhowever, to so arrange the wicks within the reservoir whereby the above mentioned difficulty may be obviated and the v therefor. v

alineme'nt with the Valve engaging ends of the rocker arms, vertically arranged tubes extendingA through the openings and having their lower ends spaced from the rocker arms and out of the pathof movement of the latter, a lubricant reservoir lixed to said tubes, with the latter extending therein andterminating at their upper ends adjacent the top wall of the reservoir, disc- L like elements threaded to said tubes and engaging opposite faces of the top walls of the cover to permit the reservoir to be adjusted towardsA stems of the valves, said wicks extending out of the upper ends of the tubes and depending about the upper portion of the tubes Within the lubricant of the reservoir and contacting With the bottom Wall of the reservoir, and caps engaging over the upper ends of the tubes and clamping the wicks to the tubes against displacement endwise of said tubes.
